Surgery for idiopathic full-thickness macular holes within four months of symptom onset yields superior visual outcomes: Results from an Irish patient cohort.

PURPOSE: To describe the anatomical, visual, and safety results of full-thickness macular hole (FTMH) repair surgery and determine factors influencing outcomes. PATIENTS AND METHODS: A retrospective chart review was performed on all patients who underwent primary FTMH repair surgery by a single surgeon over a 3-year period. For comparisons, Snellen visual acuity (VA) was converted to logMAR equivalent. Anatomical hole closure, visual improvement, and final VA of ≤ 0.30 logMAR were the primary outcome measures. RESULTS: Twenty eyes of 19 patients were included. Mean patient age was 69 years (range 55 to 80 years) and 74% were female. Mean minimum linear diameter (MLD) was 440 µm (range 170 µm to 1200 µm). Mean duration of symptoms before surgery was 16 weeks (range 3 to 39 weeks). 100% of eyes achieved successful anatomical FTMH closure. Mean VA improved from 1.03 ± 0.43 logMAR (Snellen 6/60) preoperatively to 0.35 ± 0.22 logMAR (Snellen 6/15) postoperatively (p = 0.0001). Patients with worse preoperative VA gained more vision than those with better preoperative VA (p = 0.01). Eyes operated on within 4 months of symptom onset were more than twice as likely to achieve a postoperative VA of ≤ 0.30 logMAR (Snellen 6/12 or better) compared to eyes with a longer duration of symptoms (p = 0.03). CONCLUSION: FTMH repair surgery was safe and effective, with outcomes comparing favourably with published international studies. All patients benefited from surgery regardless of symptom duration, presenting VA or FTMH size. However, surgery performed within 4 months of symptom-onset was particularly beneficial, highlighting the need for prompt referral and surgery.

Early vitrectomy is indicated for both diffuse and dense vitreous haemorrhages of unknown aetiology.

BACKGROUND: Early vitrectomy for complete fundus-obscuring vitreous haemorrhage (VH) allows for prompt diagnosis and treatment of the cause. AIMS: To analyse the causes of VH of unknown aetiology, whether partially fundus-obscuring or dense, and to determine the outcomes of early vitrectomy. METHODS: A retrospective review of patients who underwent early vitrectomy within 10 days of symptom-onset for partially fundus-obscuring or dense VH of unknown origin. Patients with evidence of proliferative diabetic retinopathy in either eye or any other preoperatively diagnosed aetiology of VH were excluded. RESULTS: 19 patients were included. Intraoperative diagnoses were: retinal tears without rhegmatogenous retinal detachment (RRD) (53%); peripheral localised RRD (32%); neovascularisation secondary to retinal vein occlusion (11%) and posterior vitreous detachment without a retinal break (5%). Patients with diffuse VH were as likely to have a retinal tear diagnosed as those with dense VH (88% vs 82%, respectively; p = 0.7). Mean VA improved from 1.26 LogMAR to 0.23 LogMAR postoperatively (p = 0.001). 1 patient (5%) developed a RRD one-year postoperatively. CONCLUSIONS: In cases of diffuse or dense VH of unknown aetiology, an occult retinal tear should be suspected. Early vitrectomy should be strongly considered regardless of whether the fundal view is partially or completely obscured, to prevent progression to visually significant RRDs.

Evaluation of Inflammation in the Peripheral Multiple Sclerosis Retina Using Ultra-Widefield Optical Coherence Tomography: A Pilot Study.

BACKGROUND AND OBJECTIVE: Reports of fundus fluorescein angiography (FFA) in active multiple sclerosis (MS) have shown peripheral perivenous sheathing. We sought to assess the feasibility of ultra-widefield (UWF) FFA and optical coherence tomography (OCT) in assessing the peripheral retina in MS. MATERIALS AND METHODS: Participants with MS and healthy controls underwent bilateral UWF fundus photography and FFA. Swept-source OCTs were captured centrally, peripherally, and to delineate any abnormalities visualized. RESULTS: We recruited five people with relapsing remitting MS, with a mean age of 36.9 (± 9.9), mean disease duration of 11 years (± 6.3), and a median expanded disability status score of 0.75 (0 to 2.5). In all MS participants, the disease was not active clinically or radiologically. Using UWF-FFA and OCT, we did not detect clear evidence of peripheral retinal abnormalities, which is consistent with the participants having inactive MS. CONCLUSION: A pilot study using UWF-FFA and peripheral OCT to examine the retina in MS suggests that it may be useful to perform a larger prospective longitudinal study to establish its potential as a monitor of disease activity.
