To evaluate the relation between macular hole volume (MHV) and postoperative central macular thickness (CMT) via spectral-domain optical coherence tomography (SD-OCT).
The present retrospective study was conducted in Department of Ophthalmology, Dokuz Eylul University School of Medicine, Izmir, Turkey.
Thirty-three eyes of 30 patients with the diagnosis of grade 3 or 4 macular hole who underwent chromovitrectomy combined with internal limiting membrane peeling surgery were enrolled. Complete ophthalmologic examination including best corrected visual acuity (BCVA), slit-lamp examination, ocular tonometry, dilated fundoscopy, and SD-OCT were performed in pre and postoperative visits in all participants. MHV was measured from the preoperative SD-OCT scan that captured the widest cross-sectional image of the hole.
Of the 30 patients with the mean age of 63.9±11.0 years (15–76), 18 (60.0%)were females and 12 (40.0%) were males. Mean preoperative BCVA, intraocular pressure (IOP) and MHV were logMAR 0.99±0.36 (0.3–2.0), 14.7±2.1 mmHg (11–20) and 0.139±0.076 mm3 (0.004–0.318), respectively. However the abnormality was present in foveal inner segment – outer segment (ISOS) junction in all participants preoperatively, SD-OCT scans revealed the reestablishment of ISOS junction in 13 eyes (39.4%) after the mean follow-up of 16.3±14.3 months (3–50). Mean BCVA and IOP were measured as logMAR 0.64±0.38 (0.0–1.6) and 14.6±1.9 mmHg (11–20), respectively in the last follow-up visit. Although early anatomical success was achieved with macular hole surgery in all cases, recurrence was faced in 4 eyes (12.1%) at the late follow-up visits. Mean CMT that was measured at the last follow-up visit, was found as 187.6±67.8 micrometrs (60–367) in the remaining 29 patients. There was no statistical significance between MHV and the frequency of hole recurrence (p=0.544). Although no statistical correlation was found between MHV and postoperative visual acuity (p=0.588), a negative correlation was present between MHV and CMT that was measured at the last follow-up visit (p=0.04).
Although anatomical success is generally achieved with macular hole surgery, postoperative visual acuity may not improve in some patients which may be related with the postoperative macular atrophy. In the present study greater MHV was found to be related with lower postoperative CMT scores.
