Fundus autofluorescence imaging using a confocal scanning laser ophthalmoscope is a useful technique to identify FAF characteristics in patients with nonexudative AMD. Different patterns of FAF abnormalities can be obtained in these eyes. Our results indicate that patchy, linear, and reticular patterns are the specific patterns associated with CNV development in nonexudative AMD.

Background/Objective: To evaluate if fundus autofluorescence (FAF) patterns around geographic atrophy (GA) and the status of the fellow eye have an impact on GA progression. Methods: We included 54 eyes of 35 patients with GA. Areas of GA were quantified by RegionFinder software. Results: GA progression rates in eyes with a diffuse trickling pattern (median 1.42 mm²/year) were significantly higher than in normal eyes (median 0.22 mm²/year) and eyes with other diffuse FAF patterns (median 0.46 mm²/year). Eyes with a banded pattern had a significantly higher progression rate (median 0.81 mm²/year) than those without any FAF abnormalities (p = 0.038). The group with baseline total atrophy of the eyes <1 disk area (DA; median 0.42 mm²) had an inverse relation with GA progression compared to the groups with baseline atrophy >1 DA (p < 0.05). Conclusion: Diffuse trickling and banded patterns may have an impact on GA progression and may serve as prognostic factors.

Purpose: To compare lateral rectus recession (LRc) and medial rectus advancement (MRadv) for correction of consecutive exotropia (CXT). Methods: Of the 43 exotropic patients 20 of them underwent LRc (group 1) and 23 of them underwent MRadv (group 2). Postoperative exodrift, strabismic angle, dose effect relationship were compared with minimum 2 years follow‑up. Results: An average dose-effect in group 2 is higher than group 1 in the early postoperative period, however there was no significant difference at the second year follow-up (p=0,109). An average exodrift after 2 year follow-up was 6,6±7,12 PD in group 1, and 8,13±7,45 PD in group 2. Postoperative overall success rate was 50% in group 1 and 65% in group 2 at the last follow-up. The success rates were not significantly different between the groups (chi-square, p =0.31). Conclusion: Although there was no statistically significant difference at the last follow-up, better results were obtained with MRadv than LRc in the treatment of CXT.

Objectives: To determine the normal values for retinal nerve fiber layer thickness (RNFLT) in myopic patients without glaucoma and analyze the changes in their color map. Materials and Methods: A total of 245 eyes without glaucoma were included in the study. According to the degree of myopia, the cases were divided into 4 groups: control group (+1.00/-1.00 D; n=70), Group 1 (-1.00/-3.00 D; n=50), Group 2 (-3.00/-6.00 D; n=75), and Group 3 (>-6.00 D; n=50). Intra-group comparisons were performed in terms of superotemporal, superonasal, nasal, inferonasal, inferotemporal, temporal, and global RNFLT (Heidelberg Spectralis, Optic Coherence Tomography, Germany) and the color coding of these quadrants (green: within normal limits, yellow: borderline, red: outside normal limits). Results: All groups were similar in age and gender (p>0.05). As the degree of myopia increased, RNFLT became thinner in the upper and lower temporal and upper and lower nasal quadrants (p<0.01). The rate of measurements considered borderline and outside normal limit in at least 1 quadrant was higher in groups with higher myopia for all quadrants (p<0.05). This rate was found to be 8/70 (11.4%) for the control group, 9/50 (18.0%) for Group 1, 21/75 (28.0%) for Group 2, and 33/50 (66.0%) for Group 3 (p<0.01). Conclusion: The high rate of RNFLT classified as borderline or outside normal limits in myopic patients is a finding to which clinicians should pay attention in order not to make a misdiagnosis, especially in cases of suspected glaucoma.

Two consecutive patients with anterior non-arteritic ischaemic optic neuropathy were evaluated with spectraldomain optical coherence tomography. The optical coherence tomographic scans revealed subfoveal fluid and intraretinal fluid extending from the optic disc margin toward the fovea that made us think that the submacular fluid appeared to arise from the peripapillary region. Fluorescein angiography showed no accumulation in the macular area, whereas leakage and staining of the optic nerve was present. After systemic corticosteroid therapy, the submacular fluid decreased promptly and the visual acuity improved. Subretinal-fluid-associated disc oedema may develop in some patients with NAION and contribute to the visual loss associated with this condition. Optical coherence tomography should be performed to follow macular involvement in patients with neuro-ophthalmic disease as well as to monitor patients' response to treatment.
