Rationale: Conjunctival papilloma is a benign neoplastic lesion of epithelial origin, with a minimal tendency toward malignancy and an exophytic growth type. Etiological factors that contribute to the appearance of papilloma are UV exposure, HPV infection, smoking, and immunodeficiency. A case report of limbal conjunctival papilloma treatment with topical interferon alpha-2b eye drops applied to the conjunctival sac. Patient concerns: A 49-year-old female patient treated in the Clinical Department of Ophthalmology for conjunctival lesion located in the temporal quadrant near the limbus of the right eye. Ocular examination of the patient's eye did not show any abnormalities: visual acuity—20/20, intraocular pressure—16 mmHg. Diagnoses: During physical examination, a broad-based pink lesion of size 4 mm × 6 mm was found in interpalpebral bulbar conjunctiva with prominent feeder vessels and soft consistency. Lesion in the biomicroscopic examination did not show any sign of malignancy. In Swept Source Optical Coherence Tomography (SS-OCT) there was no sign of infiltration into sclera or cornea. In vivo confocal microscopy (IVCM) examination, revealed loss of the normal conjunctival epithelium - hyper-reflective cells, variation of cell size. A clinical diagnosis of limbal conjunctival papilloma was made. Interventions: Interferon alpha-2b 1 million IU/ml eye drops were applied 4 times a day for 5 months. The treatment lasted 5 months without changing the dosing regimen. Three months after the start of the interferon treatment, a complete regression of the lesion was achieved. Treatment was continued for the following 2 months. Controlled IVCM after 6 months showed only few hyper-reflective cells and fibrotic tissue. Outcomes: Treatment of conjunctival papilloma with topical interferon alpha-2b led to the complete regression of the lesion. Although after the therapy the conjunctiva appears normal both in slit lamp and in the OCT examination, there is a noticeable fibrosis of the tissue in confocal microscopy. During the 14-month follow-up period, there were no recurrent lesions. Lessons: In this study, topical interferon alpha-2b has been shown to be an effective and safe therapy for small-to-medium-size conjunctival papilloma without any sign of malignancy.

Purpose. This study aims to assess scleral and conjunctival thickness using optical coherence tomography after ultrasound ciliary plasty (UCP) procedure with reference to scleral marks appearing in the area where the ultrasound energy was applied. Materials and Methods. Seventy-eight patients with primary and secondary refractory glaucoma participated in this study. Complete ophthalmic examinations including measurements of scleral and conjunctival thickness were performed preoperatively and at 1 week, and 1, 3, 6, 12, 18, and 24 months postoperatively. The parameters were determined using the Swept Source OCT with anterior attachment. Thirty-eight patients (58 scleral marks—23 superior and 35 inferior) fulfilled the inclusion criteria and completed the follow-up period of 24 months. Results. The mean ± SD scleral and conjunctival thickness in superior scleral mark before the procedure and at 1 week, and 1, 3, 6, 12, 18, and 24 months after the procedure was 684.57 ± 83.58 μm, 771.78 ± 112.03 μm (p<0.001), 771.74 ± 100.12 μm (p<0.001), 731.38 ± 83.92 μm (p=0.012), 719.52 ± 73.20 μm (p=0.037), 702.91 ± 66.50 μm (p=0.247), 694.13 ± 72.22 μm (p=0.482), and 699.35 ± 70.68 μm (p=0.200), respectively. The mean ± SD scleral and conjunctival thickness in inferior scleral mark before the procedure and at 1 week, and 1, 3, 6, 12, 18, and 24 months after the procedure was 816.86 ± 79.30 μm, 936.37 ± 107.33 μm (p<0.001), 946.00 ± 130.40 μm (p<0.001), 896.63 ± 123.40 μm (p<0.001), 877.69 ± 114.38 μm (p=0.003), 843.03 ± 71.55 μm (p=0.021), 811.86 ± 68.91 μm (p=0.731), and 805.03 ± 69.52 μm (p=0.248), respectively. The transient thickening of the sclera was observed after the procedure; however, after 12 months postoperatively, the parameters returned to the initial value and no significant difference was noted. Conclusion. The sclera thickness increases after UCP. However, with time the thickness reduces to its initial value with no significant difference. Clinical implication of the scleral changes lasts shorter than the measured significant difference in scleral thickness.

Background: this study aimed to assess the effectiveness and safety of phaco-endocyclophotocoagulation (phaco-ECP) in patients with glaucoma over five consecutive years. Methods: Thirty-eight patients (38 eyes) with primary and secondary glaucoma were enrolled to undergo phaco-ECP (Endo Optiks URAM E2, Beaver-Visitec International, Waltham, MA, USA). The primary outcome measures were intraocular pressure (IOP) reduction, success rates, glaucoma medication use, and visual acuity after phaco-ECP. An IOP reduction of 20% compared to the baseline value without re-intervention was considered a successful treatment. Complete success was defined as a cessation of antiglaucoma medications. Secondary outcome measures included intraoperative and postoperative complications. Measurements were performed preoperatively and in the first week and 1, 3, 6, 12, 18, 24, 30, 36, 42, 48, 54, and 60 months postoperatively. Results: The mean ± SD values of IOP preoperatively, at 12, 24, 36, 48, and 60 months postoperatively were 22.6 ± 6.7 mmHg, 15.9 ± 3.9 mmHg (p < 0.001), 15.9 ± 2.9 mmHg (p < 0.001), 15.6 ± 2.7 mmHg (p < 0.001), 15.5 ± 3.8 mmHg (p < 0.001), and 15.2 ± 2.6 mmHg (p < 0.001), respectively. The mean IOP at the last follow-up was reduced by 32.7%. The decrease in the number of antiglaucoma medications was statistically significant at each follow-up visit compared to the baseline. The qualified success rate was 40.6%. All patients at the 60-month follow-up visit required the use of antiglaucoma medications—none of the patients achieved complete success. During the follow-up period, nine patients (28.3%) that required retreatment due to nonachievement of the target IOP were considered failures. Six patients (15.8%) were lost from the follow-up. A total of 23 patients were evaluated 60 months after their phaco-ECP. Complications directly associated with the procedure, such as corneal edema (25.6%), IOP spikes (20.5%), IOL dislocation (2.6%), and uveitis (12.8%), were observed in our patients. Hypotony was not observed in any of our patients. Conclusions: The phaco-ECP procedure was effective, well-tolerated, and safe for reducing IOP in glaucoma patients with cataracts over a long-term follow-up. Randomized, larger-scale studies are required to validate the results obtained.

The aim was to assess the trends in optical coherence tomography angiography (OCTA) use compared with fluorescein angiography (FA).A bilateral patient’s exam on a single day was considered one exam...

Background: This study assessed the efficacy and safety of Ahmed valve implantation in patients with aniridic glaucoma for three consecutive years. Methods: Six adult patients (seven eyes) with Ahmed valve (AV) implants for aniridic glaucoma were enrolled in the study. The primary outcome measures were intraocular pressure reduction, glaucoma medication use, success rates, and visual acuity after AV implantation. A 30% reduction in IOP from baseline without the need for re-intervention was considered an effective treatment. The cessation of antiglaucoma medications was defined as complete success. Intraoperative and postoperative complications were included as secondary outcome measures. Measurements were performed preoperatively, at the first week, and 1, 3, 6, 12, 18, 24, 30, and 36 months postoperatively. Results: A total of seven eyes (6 patients) were evaluated 36 months after AV implantation. The mean ± SD values of IOP preoperatively at 1 day, 1 week, and 1, 3, 6, 12, 18, 24, 30, and 36 months postoperatively were 30.4 ± 4.0 mmHg, 14.6 ± 4.6 mmHg, 16.1 ± 4.6 mmHg, 20.7 ± 7.0 mmHg, 14.5 ± 2.7 mmHg, 16.5 ± 5.9 mmHg, 16.2 ± 4.0 mmHg, 16.3 ± 4.3 mmHg, 17.2 ± 10.1 mmHg, 17.6 ± 6.9 mmHg, and 18.2 ± 5.5 mmHg, respectively. At the last follow up, the mean IOP was reduced by 40.2%. The qualified success rate was 85.7%. One patient (one eye) at the last follow-up visit did not require antiglaucoma medications, resulting in a complete success rate of 14.3%. Intra- and postoperative mild or moderate subconjunctival bleeding was observed in all the patients. No other major/minor intraoperative or postoperative complications were noted. Conclusions: In long-term follow up, the AV implantation procedure is well-tolerated and relatively safe for reducing IOP in adult aniridia patients with glaucoma. These results should be validated through studies involving a larger patient cohort.
