Outcomes of Gonioscopy-Assisted Transluminal Trabeculotomy as a Primary Surgical Treatment for Glaucoma Secondary to Juvenile Idiopathic Arthritis-Associated Uveitis.

Gonioscopy-assisted transluminal trabeculotomy (GATT) has been used as a safe and effective procedure in the treatment of open angle glaucoma. In the present report, we demonstrated successful IOP control in two uveitic glaucoma cases secondary to juvenile idiopathic arthritis (JIA) following 360° GATT. Case 1 was a 7-year-old pseudophakic male with a preoperative IOP of 38 mmHg; his IOP stabilized at 17 mmHg with two topical antiglaucoma medications over 18 months. Case 2 was a 8-year-old aphakic male with a preoperative IOP of 42 mmHg; his IOP decreased to 12 mmHg over 15 months. We observed postoperative IOP spike in case 1 which was successfully controlled conservatively. Peripheral anterior synechia formation also occured in both cases during follow-up. One should be vigilant for possible complications after GATT in such cases. As glaucoma surgery success can have a tendency to decline with time in pediatric cases with uveitis-associated glaucoma, we believe that further evidence is still required to shed more light about the benefits of GATT technique in complex cases of pediatric secondary glaucoma subtypes like JIAU-induced glaucoma.

Evaluation of peripheral anterior synechia formation following gonioscopy-assisted transluminal trabeculotomy surgery.

PURPOSE: To quantitatively assess the development of peripheral anterior synechia (PAS) formation rate and PAS locations on gonioscopic examination following gonioscopy-assisted transluminal trabeculotomy (GATT) surgery and investigate the surgical outcomes. METHODS: A total of 35 eyes from 31 patients with open angle glaucoma who underwent GATT or combined GATT and phacoemulsification surgery were analyzed. Presence of PAS was assessed on gonioscopy in nasal, temporal, superior and inferior quadrants at months 1, 3 and 6 following surgery. Surgical outcomes were also noted. RESULTS: Frequencies of PAS formation were 38.3%, 25.3%, 17.0% and 19.1% at postoperative 1 month, 34.0%, 26.4%, 17% and 22.6% at postoperative 3 months and 32.3%, 25.8%, 16.1% and 25.8% at postoperative 6 months, in nasal, temporal, superior and inferior quadrants, respectively. The highest amount of PAS involvement was 3 clock hours in the study which was identified only in nasal and inferior quadrants. Frequency of PAS formation did not significantly differ between nasal, temporal, superior and inferior quadrants at all time points (p > 0.05). No significant differences of mean IOP levels were observed between patients who developed PAS and who did not develop PAS at postoperative 1 month (p = 0.72), 3 months (p = 0.21) and 6 months (p = 0.59). The mean IOP and mean number of antiglaucoma medications decreased from 31.5 ± 7.2 mmHg and 3.6 ± 0.6 at baseline to 13.8 ± 3.1 mmHg and 1.6 ± 1.3 at postoperative 6 months, respectively (p < 0.001, for both). Cumulative success rate (95% confidence interval) was 74.3% (69.9-78.6%) at the end of the study. Mild to moderate degrees of hyphema occurred in all cases postoperatively. CONCLUSION: Although PAS formation was observed to be relatively higher in nasal quadrant, PAS frequency was not statistically different between the angle quadrants.

Psoriasis and uveitis.

PURPOSE: Psoriasis, which is a chronic, immune-mediated skin disease of unknown etiology, not only affects the skin, but also is linked to many systemic conditions such as arthritis, cardiovascular disease, depression, and malignancy. Although many types of eye involvement are encountered in psoriasis patients, dry eye is the first among them. Uveitis is an entity that can be associated with psoriasis and can cause severe vision loss as a result of late diagnosis, inadequate and inappropriate treatment. In this review, we aimed to shed light on the diagnosis, type, prognosis and treatment of uveitis in psoriasis patients by compiling current datas obtained from published studies and to guide the follow-up and treatment of these patients. METHODS: A systematic literature search was done on PubMed using key words including "psoriasis", "psoriatic arthritis", "uveitis", "TNF- inhibitors", "HLA B27". RESULTS: In the literature, the frequency, type and treatment of uveitis developing in the course of psoriatic arthritis are clearly defined. However, the coexistence of psoriasis and uveitis has not yet been clarified due to few numbers published studies and designs of these studies. Since we examined the existing studies, we determined that the coexistence of psoriasis and uveitis could be acute or insidious, and the probability and severity of uveitis increased as the severity of skin and joint involvement increased. In addition, we found that psoriasis-associated uveitis can be bilateral, chronic, severe progression and with a high recurrence rate. CONCLUSION: The relations between non-arthritic psoriasis and uveitis have not yet been fully elucidated. Physicians who treat these diseases must be cautious, and refer their patients who have psoriasis to an ophthalmologist for periodic examination, even if they do not have eye symptoms. On the other hand, ophthalmologists must be careful in uveitis patients in terms of skin and joint involvement, and must not overlook the underlying disease.

Long-Term Follow-Up Results of a Patient Undergoing Acute Retinal Necrosis: A Case Report and Literature Review.

PURPOSE: To describe the follow-up and treatment approach of a patient with acute retinal necrosis. Case Report. A 44-year-old male patient, who had complaints of pain in the right eye and blurred vision, was referred to our clinic. Best-corrected visual acuity (BCVA) was 0.4. There was 2+ anterior chamber reaction and diffuse smooth-rounded keratic precipitates. Fundus examination revealed optic nerve and vascular involvement. Fundus fluorescein angiography revealed extensive ischemia in the periphery. Oral antiviral therapy was preferred. In addition, systemic steroid and laser photocoagulation were applied. Nonetheless, retinal detachment developed 2 months later. Detachment, silicon removal, and cataract surgery were performed sequentially. It was observed that the patient was followed for 4.5 years and did not have contralateral eye involvement. Best-corrected visual acuity remained stable at 0.3. CONCLUSION: Early diagnosis, appropriate treatment, accurate complication management, and frequent follow-up may provide useful vision in patients with acute retinal necrosis.

The efficacy of subthreshold micropulse yellow laser (577 nm) in chronic central serous chorioretinopathy.

Central serous chorioretinopathy (CSC) is a disease characterized by a well-defined serous detachment of the neurosensory retina. Therapeutic options in chronic cases are limited, and side effects can result in a limited response. The aim of this article is to assess the efficacy of subthreshold micropulse laser therapy in patients with chronic central serous chorioretinopathy. The study included 20 eyes of 19 patients who had a history of chronic or chronic recurrent CSC and who underwent subthreshold micropulse laser therapy between January 2015 and June 2018. Twenty eyes of 19 patients with a mean age of 48.9 ± 9.40 years were included. The mean visual acuity was 0.24 ± 0.28 logMAR before laser, 0.19 ± 0.25 logMAR 3 months after laser, and 0.18 ± 0.27 logMAR after 6 months. A statistically significant difference was determined in terms of visual acuity before and after treatment (p = 0.0001). The mean central retinal thickness was 308.10 ± 95.25 µm before laser, 233.65 ± 81.17 µm 3 months after laser, and 203.88 ± 72.79 µm at 6 months. A statistically significant relationship was present between visual acuity and the duration of disease (p = 0.001), between visual acuity and the outer nuclear layer thickness (p = 0.005), and between the outer nuclear layer thickness and the duration of disease in chronic cases (p = 0.008). There was no evidence of retinal pigment epithelium or retinal damage on optical coherence tomography or fundus autofluorescence secondary to subthreshold micropulse laser therapy. Visual acuity appears to be more associated with the duration of disease and with changes in the outer nuclear layer thickness in chronic CSC. Subthreshold micropulse laser therapy seems to be effective at treating chronic CSC, while it increases success during early period of the disease before the development of permanent retinal damage.

Characteristics and Seasonal Variations of Rhegmatogenous Retinal Detachment in the Eastern Black Sea Region of Turkey: 8-Year Results.

Objectives: To assess seasonal variations in the incidence of rhegmatogenous retinal detachment (RRD) in the Eastern Black Sea region of Turkey. Materials and Methods: Patients presenting due to primary RRD to a university hospital operating as a reference clinic in the region between 2011 and 2018 were evaluated retrospectively. Patients' ages, sex, affected eye, and presentation times were recorded. Years were divided into months, quarters, seasons, and half-year periods, and these periods were analyzed in terms of differences in patient numbers. Results: Two hundred eighty-one eyes of 276 patients meeting the study criteria were included. The patients' mean age was 60.2 years, and the male:female ratio was 1.35:1. Right and left eye rates were similar. Detachments were most common (49.4%) in the upper temporal quadrant. Eighty-nine patients (31.6%) had undergone uncomplicated phacoemulsification surgery a mean 2.7 years previously. The mean annual case number was 35.13±5.43, and no statistically significant variation was determined in case numbers by year (p=0.558). Analysis of all years revealed a monthly mean case number of 23.42±4.4, with the highest number of cases, 29 (10.3%), being seen in September and the lowest number, 13 (4.7%), in December. No statistically significant monthly variation was determined (p=0.613). Similarly, no statistically significant variation was observed in case numbers analyzed by quarter, season, or half-year (p>0.05). Conclusion: The incidence of cases of uncomplicated RRD does not exhibit seasonal variation in our region. We also think that since 31.6% had a history of cataract surgery, patients undergoing phacoemulsification surgery, even if uncomplicated, should be periodically assessed for detachment.
