*3.1.4 Complications after stereotactic radiosurgery: Our results*

The fundamental objective of radioactive therapy is to control malignancy while maintaining useful vision. Present techniques result in a high incidence of tumor control for intermediate and small lesions (< 8 mm in height). Tumor control for enormous sores is not ideal, also, here is a higher frequency of late complexities bringing about hindered vision in huge sores. All things considered, radiation portion decrease to the uninvolved piece of the eye will lessen the rate of late difficulties while keeping up a high occurrence of tumor control for more modest tumors.

Utilizing of 3-D radiation dosimetry is accepted that will have significant advantage as far as therapy enhancement and lower frequency of late inconveniences. Such a 3-D framework grants exact pre-treatment arranging and adjustments of the arrangement at short notification, for example, on account of new intraoperative discoveries. There is overpowering proof that threatening melanoma of the uveal plot can be dealt with securely with radioactive plaques with long haul endurance rates equivalent to those of enucleation. We think, that the vessels around the optic plate are harmed by full portion light, prompting retinal ischemia, and this courtesies the presence of neovascular glaucoma. Safeguarding of the eye work is normal in most of radioactive-plaque treatment treated patients. Utilization of low energy isotopes, collimation of individual seeds, and routine utilization of 3-D imaging and 3-D dosimetry should assist with promoting improve episcleral plaque treatment. In writing the rate of post-radiotherapy enucleation from all causes is about 20%. The diminishing of the occurrence of intricacies as waterfall, radiation papillitis, radiation maculopathy, optional glaucoma is because of extremely exacting signs of back uveal melanoma. Today, no randomized planned investigation of the impact of the elective moderate medicines for choroidal melanoma on visual result have been performed.

In our group of patients after Ru106/Rh106 plaque treatment the accompanying late intricacies prompted crumbling of visual keenness and were seen at the last subsequent assessment:


The patient will develop radiation cataract if more than 30% of the periphery of the lens is irradiated. If the diameter of the tumor is large, invasion of the iris may occur, or if the anterior margin of the tumor is well in front of the equator, the lens may be more sensitive to irradiation. Post-radiation cataracts can occur even if less than 30% of its periphery is irradiated.

Our clinical experience shows that auxiliary enucleation after stereotactic radiosurgery because of light neuropathy and optional glaucoma was essential just in 11.5% in 3 to 5 years stretch after illumination.

#### *3.1.5 Follow-up*

The patient after SRS is controlled regularly ambulatory, the clinical and MRI examinations are carried out, which are made ambulatory, initially and MRI is controlled after 3 months after SRS, first year, next two years in half yearly intervals, then 1 time a year in a following 5 years. Patient is monitored by an ophthalmologist in 2 weeks, later 6 weeks and 3 months interval - visual acuity, intraocular pressure, slit lamp examination, fundus photo, ultrasound – B-scan, OCT, perimetry. In 3-months' interval patient is send to MRI control [2, 17, 18].

### **4. Discussion**

Fifty years back, enucleation was the main acknowledged choice of treatment for melanoma, perception until recorded development was supported for little tumors that could not be unquestionably analyzed as melanomas on beginning introduction. These days with the openness and showed sufficiency of eyeballsparing medicines, a conflict can be made for before treatment of these vague lessions. Data from the COMS primers reveals that melanoma-related mortality varies with tumor size at period of treatment. For medium estimated tumors (portrayed as tumors 2.5 to 10 mm in apical height and up to 16 mm in greatest basal width), melanoma-express mortality was 10% at five years, and 18% at 10 years. For huge tumors (those astounding the size models for medium tumors in either apical height or greatest basal expansiveness; or peripapillary tumors with an apical height more conspicuous than 8 mm), the rates extended to generally 27% at five years and 40% at 10 years. Also, as referenced above, archived development before treatment has been demonstrated to be a danger factor for metastasis. In any case, development might be a marker for more forceful tumors, and it has not been demonstrated that treating these tumors prior diminishes mortality [7].

Our present strategies for radiotherapy consider powerful nearby tumor control with eyeball preservation, yet visual morbidity is still high. In this manner, it is important to gauge the mortality hazard caused via cautious perception before treatment of uncertain sores against the outcomes of visual misfortune actuated by treatment.

In a small COMS tumor observation study, there were six melanoma-related transitions from a cohort of 67 tumor patients treated after baseline perception. Only two of these transitions occurred within five years of enrollment, resulting in an inaccurate five-year death rate with an explicit melanoma of 3% [11].

One-portion LINAC radiotherapy/radiosurgery is an abnormal way to deal with treatment of choroidal melanoma. Hypofractionation with a wide shoulder in straight quadratic model is still in conversation for radioresistant tumors like choroidal melanoma. In this examination we assessed nearby disappointment prompting enucleation as an end point in patients treated by SRS with long haul development having accumulated at the hour of investigation [19].

Picture combination of a differentiation improved attractive reverberation imaging (MRI) and figured tomography (CT) is utilized for treatment arranging co-ordinates. A few creators incline toward light before enucleation for huge uveal melanoma. This treatment is utilized in a method of SRS with a solitary division managed with a valuable spatial exactness utilizing a collimating framework.

Other than expanded tumor control, poisonousness ought to hypothetically be diminished by fractionation.

Direct quickening agents (LINAC) have the upside of an attainable fractionation. Most LINAC contemplates utilize a hypo fractionated plan of 4–5 portions and complete dosages somewhere in the range of 50.0 and 70.0 Gy. The viability of SRT for uveal melanoma has been demonstrated in various investigations with neighborhood tumor control rates announced over 90%, 5 and 10 years after treatment. Radiogenic results after SRT are accounted for also to different types of radiotherapy, with waterfall advancement, radiation retinopathy, opticopathy and neovascular glaucoma being liable for most of optional vision misfortunes and auxiliary enucleations. Generally speaking, stereotactic photon bar radiotherapies (SRS and SRT) are viewed as compelling treatment modalities for uveal melanoma, with promising late tumor control and poisonousness rates. SRS is a generally new strategy, so there is a requirement for multi-focus preliminary to contrast the results following stereotactic radiosurgery and different techniques. Nonetheless, as of recently, no investigation has been acted in this point. Studies contrasting endurance rates following enucleation versus more current treatment modalities, including SRS, recommended comparative rates for tantamount sores and in light of the fact that revealed nearby tumor control rate following SRS seem similar, we offer SRS to patients who might somehow or another require enucleation [1].

Stereotactic photon treatment of uveal melanoma, in light of CT and MRI pictures, is a protected and exact treatment choice. Neighborhood control was discovered to be superb. Due to choice models, the quantity of patients in the investigation with decreased visual sharpness will likely expansion later on.

Neighborhood power over 95% shows up in certain investigations: in the investigation of Dieckmann nearby control is 98% after a middle perception time 33 months follow up. The perception time is still too short to even consider allowing complete ends, yet their outcomes are tantamount with the 82–98% nearby control rate detailed by different gatherings after a middle perception season of as long as 15 years [21].

Visual misfortune after proton pillar light was depicted in 33–47% following 1 and 2 years, individually, for tumors situated close to the optic plate and fovea.

Different creators announced in a review study that light of 30.0 Gy of in excess of 2 mm of the optic nerve head started an optic neuropathy.

In the investigation of Dieckmann because of troublesome tumor size and area in the region of basic structures, for example optic nerve and macula, visual decrease was seen in a high number of the patients. After a perception season of beyond what a half year visual sharpness can be assessed in 79 patients. In the gathering of 77 patients 85.5% gave visual sharpness of 0.1 or better before radiotherapy. LINAC based stereotactic light for melanoma of uvea is plausible and all around endured. Can be offered to patients with medium measured and horribly found melanoma of uvea who are looking for an eye-protecting therapy [22].

To accomplish great visual keenness result it is significant right limitation of the tumor. Brachytherapy Ru106 of back choroidal melanoma accomplishes great preservation of vision if the tumor does not stretch out near the optic nerve or fovea. Realize that the intensity of a test to look at endurance in at least two gatherings is connected not to the all out example size but rather to the quantity of functions of interest, (for example, passing for this situation). At the end of the day, the endurance tests perform better when the editing is not excessively substantial, and, specifically, when the example of controlling is comparable over the various gatherings. High number of right-blue-penciled information (from those patients who actually were alive toward the finish of perception, or exited the investigation for different reasons other than death before its end) could influence the unwavering quality of the outcomes. Subsequently, the substantial controlling may confuse the assessment of the endurance model, since it diminishes the comparable number of

Stereotactic radiosurgery and fractionated stereotactic radiotherapy have developed as promising, non-intrusive medicines for uveal melanoma [26]. Albeit, verifiably, melanoma has been viewed as a moderately radioresistant tumor, fresher information have tested this perspective, and radiation treatment is currently viewed as a helpful segment of the restorative armamentarium for harmful melanoma.

No endurance distinction inferable from stereotactic light or joined and careful mentality - enucleation of uveal melanoma has been exhibited in the review concentrate in Slovakia.

In our examination bunches researched, endurance investigation changed for indicators demonstrated that the gathering of patients after stereotactic radiosurgery had similar result as the gathering of patients treated with extremist medical procedure. In light of our examination, we expect that the endurance guess is basically dictated by the personality of the tumor in relationship to the status of the patient. Clinically, the main factors that influence the metastatic cycle are the limitation and size (volume) of the sore.

There has been played out no multicenter preliminary to survey dosimetry, wellbeing and adequacy of SRS, or to assess results of gamma knight radiosurgery for melanoma yet, yet information from a few announced case arrangement recommend that SRS could have comparative nearby tumor control rate, metastasis rate, death rate and intricacies rate when contrasted with brachytherapy. Late investigations have proposed that gamma knight radiosurgery and SRS might be a fitting option for treating uveal melanoma in those patients, in whom sores are ineligible for customary brachytherapy. The discoveries in the arrangement propose a part of SRS in the treatment of chose instances of uveal melanoma. Treatment by either essential enucleation or SRS as per our outcomes does not seem to impact the improvement of metastases in patients with uveal melanoma; the endurance anticipation is basically controlled by the stage and character of the tumor.

No endurance contrast inferable from stereotactic light or extremist careful disposition - enucleation of uveal melanoma has been shown in this review study. A little contrast is conceivable, yet a clinically significant distinction in death rates, regardless of whether from all causes or from metastatic melanoma, is far-fetched. SRS is a non-intrusive option in contrast to enucleation in the treatment of uveal melanoma with a high tumor control. There is a requirement for multi-focus preliminaries to think about the results following stereotactic radiosurgery in treatment of uveal melanoma.
