RESUMO

To analyze in vivo scleral changes induced by MicroPulse transscleral laser therapy (MP-TLT) in refractory glaucoma using anterior segment-optical coherence tomography (AS-OCT). Forty-two candidate patients for MP-TLT were consecutively enrolled and underwent AS-OCT at baseline and after six months. MP-TLT success was defined as an intraocular pressure (IOP) reduction by one-third. The main outcome measures were the mean superior (S-), inferior (I-), and total (T-) intra-scleral hypo-reflective space area (MISHA: mm2) and scleral reflectivity (S-SR, I-SR, T-SR; arbitrary scale) as in vivo biomarkers of uveoscleral aqueous humor (AH) outflow. The IOP was the secondary outcome. The relations between the baseline-to-six months differences (D) of DS-MISHA, DI-MISHA, and DT-MISHA and DS-SR, DI-SR, DT-SR, and DIOP, were investigated. At 6 months, the median IOP reduction was 21% in the failures and 38% in the successes. The baseline S-MISHA, I-MISHA, and T-MISHA did not differ between the groups, while S-SR and T-SR were higher in the successes (p < 0.05). At six months, successful and failed MP-TLTs showed a 50% increase in S-MISHA (p < 0.001; p = 0.037), whereas I-SR and T-SR reduced only in the successes (p = 0.002; p = 0.001). When comparing DS-MISHA, DI-MISHA, and DT-MISHA and DS-SR, DI-SR, and DT-SR, there were no significant differences between the groups. In the successful procedures, DIOP was positively correlated with DT-MISHA and DI-MISHA (ρ = 0.438 and ρ = 0.490; p < 0.05). MP-TLT produced potentially advantageous modifications of the sclera in refractory glaucoma. Given the partial correlation between these modifications and post-treatment IOP reduction, our study confirmed that the activation of the uveoscleral AH outflow route could significantly contribute to the IOP lowering after MP-TLT.

RESUMO

Objective: To investigate the clinical characteristics and treatment outcomes of glaucoma secondary to congenital ectropion uveae (CEU) using penetrating Schlemm's canaloplasty. Methods: This was a retrospective case series study. Medical records of patients diagnosed with glaucoma secondary to CEU and undergoing penetrating Schlemm's canaloplasty at the Eye Hospital of Wenzhou Medical University between August 2020 and December 2021 were collected. Clinical characteristics including the extent and location of iris ectropion, type of glaucoma, were analyzed. Follow-up visits were conducted at 1, 3, 6 months, and 1 year postoperatively. Visual acuity, intraocular pressure (IOP), anterior segment and fundus condition, filtering bleb morphology, use of IOP-lowering medications, ultrasound biomicroscopy results, and other indicators were analyzed to summarize surgical outcomes. Results: Six cases (6 eyes) of glaucoma secondary to CEU were included, all unilateral, with 3 left eyes and 3 right eyes; median age was 10.0 (5.3, 28.8) years; including 3 males and 3 females. Preoperative IOP was (31.7±10.0) mmHg (1 mmHg=0.133 kPa), and the preoperative number of IOP-lowering medications used was 2.0 (2.0, 3.2). The extent of iris ectropion in the 6 cases ranged from 270 ° to 360 °, with peripheral anterior synechiae corresponding to the location of iris ectropion, and angle closure with the degree of synechiae extending beyond Schwalbe's line. No surgical complications occurred in any of the 6 cases postoperatively. At 1 month postoperatively, the IOP was (16.4±3.2) mmHg, with a median of 0.0 (0.0, 1.5) medications used. At 3 months postoperatively, the IOP was (14.8±6.0) mmHg, with a median of 0.0 (0.0, 2.2) medications used. At 6 months postoperatively, the IOP was (18.1±6.1) mmHg, with a median of 0.0 (0.0, 0.5) medications used. Among them, 5 patients had a follow-up period of 1 year postoperatively, all achieving controlled IOP without the use of IOP-lowering medications, with an average IOP of (15.5±3.1) mmHg. No obvious filtering bleb formation was observed at the surgical site in all patients. Conclusions: Glaucoma secondary to CEU manifests primarily as closed-angle glaucoma, with a correspondence between the closure range of anterior iris adhesions in the angle and the extent of iris ectropion. Penetrating Schlemm's canaloplasty demonstrates favorable and stable efficacy for its treatment.

RESUMO

AIM: Secondary radiation-related side effects like secondary glaucoma (SG) of different modalities of treatment in uveal melanoma patients can appear in certain interval after therapy. This study describes the incidence of SG in patients after stereotactic radiosurgery (SRS). METHOD: The data of 230 patients treated by SRS were reviewed for SG. Group of 83 patients who were observed 5 years after treatment in one center with follow-up regularly at least 4 times per year were analyzed. RESULTS: In group of 83 patients with the median age 59 years, the median tumor volume at baseline was 0.41 cm3. The survival without SG after single dose SRS was 94 % in 1.5 year, 77 % in 2 years, 57 % in 3 years, 43 % in 3.5 years, and 18 % in 4.5 year after irradiation. In 6 patients (7.2 %) secondary enucleation was necessary due to SG. Both predictors (tumor volume and age of patient) at the time of SRS were not statistically significant by Cox proportional-hazards regression. CONCLUSIONS: Complications like SG in 5 year interval after irradiation can lead to secondary enucleation of the eye globe (Fig. 3, Ref. 44).

RESUMO

BACKGROUND: Melanoma is a life-threatening group of cancers mainly affecting the skin (cutaneous melanoma, CM) and the eyes (uveal melanoma, UM). Nearly half of patients with UM develop liver metastases regardless of the primary treatment. For this reason, adjuvant therapy to prevent disease progression is essential to improve survival of patients with melanoma. Beta-adrenoceptors (ß-AR) have emerged as novel targets to inhibit tumor growth and dissemination in CM, but have not been investigated in UM. METHODS: The aim of this study was to comprehensively evaluate the effects of a non-selective ß-blocker in UM and CM. Propranolol was tested on four UM and two CM cell lines to determine the effects of this beta-blocker. The expression of ß-AR in UM was assessed in enucleated eyes of 36 patients. RESULTS: The results showed that propranolol exerts potent anti-proliferative effects, attenuates migration, reduces VEGF and induces cell cycle arrest and apoptosis in both UM and CM in a dose-dependent manner. Furthermore, levels of cell-free DNA released from the cells correlated to propranolol treatment and may be an indicator of treatment response. Finally, immunohistochemical analysis revealed the expression of ß1 and ß2 adrenoceptors in all UM patients, with higher expression seen in the more aggressive epithelioid versus less aggressive spindle cells. CONCLUSIONS: Collectively our data suggest that a nonselective beta-blocker may be effective against melanoma. For the first time, we show potent anti-tumor effects in UM cells following propranolol administration and expression of ß1 and ß2 adrenoceptors in patient tissue.

RESUMO

PURPOSE: The aim of this study was to evaluate the effectiveness of treatment and the restoration of the anatomic conditions (retinal reattachment) in rhegmatogenous retinal detachment treated by pars plana vitrectomy (PPV) using air as endotamponade. METHODS: Twelve patients (12 eyes) with rhegmatogenous retinal detachment were included in the study. These were eyes with retinal detachment both with and without macular involvement. During the PPV surgery, the peripheral and central part of the vitreous body was excised to eliminate the formation of vitreoretinal traction after surgery, laser therapy was performed peripherally and in retinal openings, and the eyeball was filled with filtered air. Local conditions were evaluated at 1, 7, 14, 30, 90, and 180 days after the procedure. RESULTS: The result of the patients' examination on the 30 day after surgery showed that 100% of cases achieved retinal reattachment and improved vision (best corrected visual acuity). In the long-term assessment, the final visual acuity was better in 11 patients (91.7%) compared to the initial results. On average, 7 days after the surgery, air in the eyeball occupied about one-fifth of the vitreous chamber and was completely absorbed about 10 to 14 days after surgery. CONCLUSIONS: In the above-mentioned study, very good results of treatment of open-rooted retinal detachment were achieved. The air was quickly absorbed and visual acuity improved. Owing to the relatively fast absorption time, this method could be used successfully in high altitude patients and people often travelling by airplane.

RESUMO

PURPOSE: To compare long-term surgical outcomes and complications of pars plana (PP) tube implantation with conventional anterior chamber (AC) tube implantation. MATERIALS AND METHODS: Records of patients undergoing glaucoma tube implant surgery at a single institution between 2007 and 2015 were retrospectively reviewed. Eyes were matched for glaucoma diagnosis and patient age. Demographics, baseline characteristics, and treatment outcomes were recorded. Surgical success was defined as intraocular pressure (IOP) between 6 and 21 mm Hg, no subsequent glaucoma surgeries performed, and at least light perception vision. RESULTS: Fifty-seven eyes that underwent Ahmed or Baerveldt glaucoma drainage device surgery with PP tube placement were compared with 57 eyes with AC tube placement. Mean follow-up was 43.5 months in the PP group and 35.3 months in the AC group (P=0.02). Forty-nine (86.0%) PP eyes and 46 (80.7%) AC eyes achieved surgical success (P=0.45). At last follow-up, mean IOP decreased from 29.0 to 15.1 mm Hg in the PP group (P<0.01) and from 32.7 to 15.6 mm Hg in the AC group (P<0.01). Mean number of medications decreased from 2.9 to 1.1 in the PP group (P<0.01) and from 2.8 to 1.3 in the AC group (P<0.01). Mean IOP and number of medications were similar between PP and AC groups at baseline, last follow-up, and all interim time points (P>0.05 for all). There were 16 complications in the PP group and 14 in the AC group (P=0.67). CONCLUSIONS: Long-term results of glaucoma tube implant surgery with PP versus AC implantation shows effective IOP control with similar rates of surgical success.

RESUMO

PURPOSE: To report 2-year results of deep sclerectomy (DS) with mitomycin C and the uveoscleral implant Esnoper-Clip (AJL Ophthalmics, Álava, Spain), a nonabsorbable hema implant, and the morphologic analysis of the surgical area with anterior segment optical coherence tomography (AS-OCT). MATERIALS AND METHODS: In total, 41 eyes of 41 patients with medically uncontrolled open angle glaucoma who underwent DS with the uveoscleral implant were included in this prospective interventional study. Patients were recruited and selected sequentially. All patients were followed at least for 12 months and 36 of them for 24 months. Absolute success was defined as intraocular pressure (IOP)≤18 mm Hg and ≥20% of IOP reduction without topical medication. Relative success was defined with the same criteria but with the addition of any antihypertensive medication. Primary outcomes were IOP decrease in the postoperative stage. Secondary outcomes were number of medication, best-corrected visual acuity changes, rate of goniopuncture, needle revision, and AS-OCT analysis of the bleb area. AS-OCT analysis, using Visante OCT, was performed at 1, 12, and 24 months. RESULTS: Absolute success rate was 68.3% at 12 months and 61.1% at 2 years. Relative success was 78.0% and 71.4%, at 12 and 24 months, respectively. A significant IOP decrease was observed, from 27.3±6.3 to 14.9±4.4 mm Hg at 12 months and 15.3±5.2 mm Hg at 24 months (P<0.001). There was also a significant reduction in the number of medications, dropping from a mean of 2.5 to 0.28 one year and 0.36 two years after the surgery (P<0.001). Main postoperative complications were transient: 4 eyes with seidel phenomenon at 24 hours (10.3%), 3 hyphema (7.7%), and 1 choroidal detachment (2.6%). Mean intrascleral space height, measured by AS-OCT, was 0.78 mm and it showed a significant positive correlation with IOP at 12 months. Neodymium-doped yttrium aluminium garnet laser goniopuncture was performed in 25 eyes (61%) at 12 months and in 27 (66.8%) by 24 months. CONCLUSIONS: DS with the uveoscleral implant is a safe and effective procedure to lower IOP in open angle glaucoma patients. IOP reduction is maintained over 2 years and is correlated to the postoperative height of the intrascleral bleb. Supraciliary implantation reduces intrascleral lake dependency, being a simultaneous drainage alternative to the subconjunctival pathway.

RESUMO

AIMS: To evaluate, using anterior segment optical coherence tomography (AS-OCT) and in vivo confocal microscopy (IVCM), the uveo-scleral aqueous humour (AH) outflow pathways after ultrasonic circular cyclocoagulation (UCCC). METHODS: Forty-four patients with refractory glaucoma underwent 4 or 6 s UCCC (group 1, 24 eyes; group 2, 20 eyes). UCCC was successful when the preoperative intraocular pressure (IOP) reduced by one-third. AS-OCT and IVCM were performed at baseline and at month 1 to evaluate the sclera and conjunctiva. The main outcomes were mean intra-scleral hyporeflective spaces area (MIHSA: mm2) at AS-OCT, mean density and area of conjunctival microcysts (MMD: cysts/mm2; MMA: µm2) at IVCM. The relations between MIHSA, MMA and MMD with IOP were analysed. RESULTS: Mean baseline IOP was 26.9±2.8 mm Hg in group 1 and 27.5±4.0 in group 2. Intra-scleral hyporeflective spaces and microcysts were observed in both groups, without significant differences in MIHSA, MMA and MMD. At month 1, UCCC was successful in 63.6% of patients (41.6% in group 1, 80% in group 2), and IOP reduced to 18.8±3.2 (30.1%) and 17.1±2.7 mm Hg (38.7%), respectively (p<0.001). MIHSA showed a twofold and threefold increase in group 1 and 2 (p<0.05), with a significant difference between groups (p<0.05). MMA and MMD increased in both groups (p<0.05), with values higher in group 2 (p<0.05). Significant relations were found between MIHSA and IOP in both groups (p<0.01). CONCLUSIONS: UCCC induced anatomical modifications of sclera and conjunctiva, which suggested that the trans-scleral AH outflow enhancement is one of the possible mechanisms exploited by ultrasounds to reduce IOP.

RESUMO

OBJECTIVE: The authors evaluate a group of patients with malignant uveal melanoma treated with stereotactic radiosurgery in the year. 2009-2011 on a linear accelerator LINAC. MATERIAL AND METHODS: In 2009-2011 were followed 40 patients with malignant melanoma of the uvea in stage T2 and T3 treated with stereotactic radiosurgery (LINAC), the therapeutic dose of 35,0 Gy TD, TD max 42,0 Gy. We evaluated the influence of factors (age, exposure risk structures, time) to intraocular pressure (IOP) and temporal changes in intraocular pressure after surgery between the control group and the group of patients who underwent enucleation. The normality of data distribution was tested Shapiro-Wilk W test and graphically. The relations between the parameters were tested using simple and multiple linear regression (correlation coefficient r, the significance level p). RESULTS: The mean age of the group of 40 patients with malignant melanoma of the uvea treated by one day session stereotactic radiosurgery on a linear accelerator in the year. 2009-2011 was 55.13±11.11 years. Average maximum radiation dose to sensitive structures has been the target of 12,0 Gy to the optic nerve and the ciliary 10,0 Gy. The analysis in our group confirmed that the prevalence of the tumor independent of sex, increasing with age, with most patients are diagnosed between 60 and 70 years of age. Analysis of the difference in intraocular pressure (IOP) before surgery showed no significant difference between the group of men and women (p=0.54). Using simple linear regression, we confirmed assumptions, related to IOP before stereotactic radiosurgery with age (r=-0.09, p=0.65). Multiple linear regression, we evaluated the relationship between predictors (dose at-risk structures--lens and optic nerve) and the change in IOP from the value before stereotactic radiosurgery at each time interval. Relations between predictors (Dose aperture--L, the dose of the optic nerve--O) and IOP of the file being described partial correlation coefficients after 2 weeks. For the relationship is significant correlation between the dose and the IOP in the lens at the time of 1 year, 1.5 years, and 2 years after the stereotactic radiosurgery. CONCLUSION: A single stereotactic radiosurgery on a linear accelerator LINAC is possible at a dose of 35,0 to 38,0 Gy in intraocular melanomas in stage T1 to T3. According to our results, this is a highly effective method of treatment of uveal melanomas elevation to 6 mm and a capacity of up to 0,4 cm3. Secondary glaucoma is one of the most serious causes of enucleation after one day session stereotactic radiosurgery at linear accelerator (LINAC) for uveal melanoma. The percentage of enucleation in our investigated group (17.5%) for secondary glaucoma is about the same as in other studies.

RESUMO

PURPOSE: To report the safety and the effectiveness of deep sclerectomy (DS) with a new nonabsorbable uveoscleral hema implant (Esnoper-Clip) designed to increase trabecular and uveoscleral outflow and to achieve higher intrascleral blebs. MATERIALS AND METHODS: Twenty-seven eyes of 27 patients with open-angle glaucoma, who underwent DS with an Esnoper-Clip implant, were included in this study. All patients were followed up after 12 months. RESULTS: A significant decrease in intraocular pressure was observed after surgery, changing from a preoperative mean of 26.6±5.2 mm Hg to a postoperative mean of 15.3±5 mm Hg (P<0.001) at 12 months. There was also a significant reduction in the number of glaucoma drugs needed, varying from 2.5 per patient to 0.3 (P<0.001) 1 year after surgery. The main intrascleral lake height and volume at 12 months was 0.7±0.1 mm and 3.9±1.3 mm, respectively. No intraoperative complications occurred. The main postoperative complications were a positive Seidel test result at 24 hours in 2 eyes (7.4%), hyphema in 2 eyes (7.4%), and choroidal detachment in 1 eye (3.7%). All these complications resolved successfully. The need for additional mitomycin-C injections was recorded in 4 eyes (14.8%), twice in 2 of them. Twelve eyes (44.4%) underwent postsurgical Nd:YAG laser goniopuncture with a mean time between surgery and this procedure of 4.3 months. Mean intraocular pressure after Nd:YAG laser goniopuncture decreased from 19.2 to 15.5 mm Hg (P<0.001). CONCLUSION: DS with an uveoscleral hema implant (Esnoper-Clip) is a safe and effective technique for the management of open-angle glaucoma.

RESUMO

PURPOSE: Our aim was to prospectively analyze the use of contrast-enhanced ultrasound (CEUS) in the quantitative assessment of the response of uveal melanoma (UM) to gamma-knife radiosurgery (GKR), investigating whether changes in tumor vascularization precede thickness reduction, which on average occurs at 12 months after GKR. METHODS: Ten patients with UM treated with GKR underwent sonography (US) and CEUS at baseline and at 3, 6, and 12 months after GKR. The transverse diameter, thickness, and quantitative parameters of the UM (ie, area under the curve in the wash-in phase, wash-in perfusion index, peak enhancement, and wash-in rate) were calculated by using dedicated software and compared by using Wilcoxon's signed-rank test. RESULTS: The mean tumor thickness on US was significantly less at both 6 (6.6 mm) and 12 months after GKR (5.8 mm) than it was at baseline (8.3 mm; p < 0.05, both comparisons). Compared with baseline data, the median flow quantitative parameters on CEUS were significantly changed as follows: the peak enhancement (in arbitrary units [au]) at baseline was 5 × 10(6) ; 6 months after GKR, it was 2 × 10(1) (p < 0.05), and 12 months after GKR, it was 4 × 10(1) (p < 0.05). The wash-in rate (in au) at baseline was 1 × 10(6) ; 6 months after GKR, it was 2.1 (p < 0.05), and 12 months after GKR, it was 9.3 (p < 0.05). The wash-in perfusion index (in au) at baseline was 2 × 10(7) ; 6 months after GKR, it was 7 × 10(1) (p < 0.05), and 12 months after GKR, it was 1 × 10(2) (p < 0.05). The area under the curve during the wash-in phase (in au) at baseline was 1 × 10(8) ; 12 months after GKR, it was reduced to 6 × 10(2) (p < 0.05). CONCLUSIONS: At 6 months after GKR, a reduction of tumor thickness, as detected on US, occurred in 6 of the 10 patients, whereas a reduction in all the quantitative parameters measured on CEUS occurred in all 10 patients. However, a larger population is needed to investigate whether CEUS could become the first-choice technique for monitoring the response of UM to GKR.

RESUMO

PURPOSE: To report a case of solitary pigment epithelial lesion accompanied by uveal effusion (UE) with bullous retinal detachment (RD). CASE: A 63-year-old man was referred to our hospital for RD in his right eye. Best corrected visual acuity was 20/20 and intraocular pressure was 14 mmHg in the right eye. Fundus examination showed UE in the entire peripheral zone with bullous RD in the inferior retina and a grayish-white placoid lesion with indistinct border at the level of the retinal pigment epithelium at the temporal area near the macula in the right eye. No retinal tear was found, and anterior chamber depth and axial length were within the normal range. Fluorescein angiography indicated dye leakage from the placoid lesion, but pooling of dye was not intensive. Since posterior scleritis was not excluded, a systemic corticosteroid was administered but the UE with bullous RD did not improve, thererfore, photocoagulation for the placoid lesion was performed. This gradually ameliorated the UE with bullous RD, and it resolved at 4 months after the first visit without any further recurrence. CONCLUSION: Solitary pigment epithelial lesion can cause UE with bullous RD as in multifocal posterior pigment epitheliopathy (MPPE).

RESUMO

BACKGROUND AND OBJECTIVE: To evaluate the efficacy of endocyclophotocoagulation (ECP) in patients undergoing pars plana vitrectomy for vitreoretinal disease with medically uncontrolled glaucoma. PATIENTS AND METHODS: This is a retrospective review of 12 patients who underwent 270° ECP following vitrectomy. RESULTS: Ten of the 12 patients had excellent intraocular pressure (IOP) control postoperatively, without medication in four patients and with reduced medication in six patients. IOP decreased from 26.3 ± 12.9 to 17.9 ± 6.0 at 1 month (P = .03) and 16.9 ± 4.4 at 3 months postoperatively (P = .02). Best corrected visual acuity was improved by 1 month postoperatively. The number of glaucoma agents decreased from 2.7 ± 1.1 to 1.3 ± 1.3 (P = .03). One patient with neovascular glaucoma developed hypotony. Postoperative inflammation or discomfort did not exceed what was expected for a standard vitrectomy in any patient. CONCLUSION: ECP can be effectively combined with vitrectomy; however, ECP produced unpredictable results in the two patients with neovascular glaucoma.

RESUMO

OBJECTIVES: To evaluate and compare the long-term efficacy of modified uvulopalatopharyngoplasty (mUP3) and anterior palatoplasty (AP) techniques for treating snoring in a prospective clinical trial. METHODOLOGY: Patients with total apnea-hypopnea index values < 5/per hour sleep were included in the study. Patients completed the Epworth sleepiness scale (ESS) and snoring visual analogue scale (VAS) before and 24 months after surgery, and a VAS for pain after the operation. RESULTS: Twenty-four patients were in the mUP3 group with a mean age of 42.1 +/- 11.8 years, and 26 in AP group with a mean age of 43.2 +/- 10.4 years. Snoring VAS values were significantly decreased after surgery in both groups (p < 0.025), but changes between operative groups were not statistically significant (p > 0.05). Patients' ESS scores in both groups significantly decreased (p < 0.025), but ESS score changes between groups were not significantly different (p > 0.05). Two years postoperatively, patient satisfaction was 85% in the AP group, and 70% in the mUP3 group. Pain VAS values were significantly lower in the AP group than in the mUP3 group (p < 0.001). Eight patients (33.3%) in the mUP3 group and one (7.7%) in the AP group reported nasal regurgitation of liquids upon swallowing during the first week postoperatively. Two years after the operation, 10 patients (41.6%) in the mUP3 group and 9 (34.6%) in AP group still had a lump sensation in the throat. CONCLUSIONS: We compared the efficacy of the mUP3 and AP techniques to treat patients with primary snoring and found less morbidity and more patient satisfaction in the AP group.

RESUMO

Cataract is frequently associated with vitreoretinal diseases. Moreover, cataract is also a constant complication of vitrectomy in patients over 50 years. Its occurrence may be very early, especially when internal tamponade is used. For these reasons, a combined procedure including phacoemulsification and vitrectomy accelerates functional rehabilitation of patients, avoiding the need for a second operation. Interventions, their tricks and indications, are described for epimacular membranes, macular holes, diabetic retinopathy and macular hematoma. Combined surgery is a safe and effective procedure whose results are comparable to those of sequential surgery.

RESUMO

PURPOSE: To describe the outcome of intraocular tumor resection by partial lamellar sclerouvectomy (PLSU) in the pediatric age group. DESIGN: Retrospective, interventional case series. PARTICIPANTS: We included 37 patients who underwent PLSU for intraocular tumors under age 21 years. METHODS: Medical records were reviewed for clinical, operative, and histopathologic features. MAIN OUTCOME MEASURES: Globe salvage, visual acuity, surgical side effects, tumor control, and tumor-related metastasis and death. RESULTS: The mean patient age was 9 years (median, 10; range, 0.25-17) and there were 22 (59%) females and 15 (41%) males. The tumor involved mainly the iris (n = 27; 73%), ciliary body (n = 7; 19%), or choroid (n = 3; 8%). The mean tumor basal dimension was 7 mm (median, 6; range, 3-15) and thickness was 3.6 mm (median, 3; range, 0.2-9.6). The histopathologic diagnosis was melanoma (n = 19; 51%), cyst (n = 5; 14%), medulloepithelioma (n = 4; 10%), melanocytoma (n = 3; 8%), lacrimal gland choristoma (n = 2; 5%), gliosis (n = 1; 3%), nevus (n = 1; 3%), hemorrhage (n = 1; 3%), and leiomyoma (n = 1; 3%). Intraoperative adverse effects included vitreous loss in 19 (51%) and hyphema in 4 (11%). Postoperative side effects included early transient hyphema in 9 (24%) and late cataract in 12 (32%). Local tumor recurrence was detected in 5 cases (13%) at mean interval of 28 months, including melanoma (n = 3) and medulloepithelioma (n = 2). Enucleation was necessary in 9 (24%) cases for recurrence in 3 (8%), prophylactic in eyes with high-grade malignancy in 5 (13%), and for blind painful eye in 1 (3%). Of the 28 salvaged eyes, final visual acuity was ≥ 20/40 in 18 (64%), 20/50 to 20/100 in 5 (18%), and <20/200 in 5 (18%). There were no cases of metastasis or death at a mean of 51 months of follow-up. CONCLUSIONS: A surgically challenging procedure, PLSU can achieve control of selected intraocular tumors. Medulloepithelioma responds poorly to local resection and in most cases enucleation is required. If the globe is salvaged, visual acuity is ≥ 20/40 in 64% of children.

RESUMO

PURPOSE: To evaluate anatomical and functional results of 25-gauge transconjunctival sutureless pars plana vitrectomy in patients with uveitis. METHODS: Vitrectomy was performed on 20 eyes with residual vitritis secondary to infectious and noninfectious uveitis. Patients were evaluated 1 week before surgery and after surgery at day 1, week 1, week 4 and week 12. Visual acuity (VA), intraocular pressure, anterior chamber cells and flare and vitreous haze were measured. RESULTS: Mean VA improved from 2.06 ± 0.94 logMAR before surgery to 0.58 ± 0.46 logMAR at week 12 (p<0.05). No case required conversion to standard 20-gauge instrumentation or suture placement, no intraoperative complications were noted. Transient postoperative hypotony was seen in three eyes. One patient with toxoplasmic retinochoroiditis had a relapse during follow-up. CONCLUSION: 25-gauge vitrectomy has proven its efficacy on cleansing vitreous opacities and improving visual acuity on patients with residual vitritis secondary to uveitis with minimal postoperative inflammation and complications.
