PURPOSE: Eyes with relative anterior microphthalmos (RAM) (normal [ > 20.0 mm] axial length but disproportionally small anterior segment [horizontal corneal diameter < 11 mm]) often present with increased intraocular pressure. Under these difficult conditions cataract surgery alone or in combination with a glaucoma filtering procedure is often required. PATIENTS AND METHODS: We retrospectively reviewed the records of 71 patients (108 eyes) with RAM in whom cataract only (n = 72) or combined cataract/glaucoma surgery (n = 36) was performed. Preoperative clinical and biometric findings, intraoperative complications and postoperative results (visual acuity and intraocular pressure) were analysed. RESULTS: Median preoperative values were 7.46 mm for corneal curvature, 2.53 mm for anterior chamber depth and 22.44 mm for axial length. The implanted lens had a median 25.0 dioptric power. The IOP was reduced from 15.6 ± 3.9 mmHg to 13.5 ± 3.1 mmHg with cataract surgery alone and from 22.4 ± 5.5 mmHg to 15.4 ± 4.0 mmHg with combined surgery. Mean best corrected visual acuity improved from 0.4 ± 0.2 to 0.79 ± 0.25 with cataract surgery and from 0.5 ± 0.3 to 0.81 ± 0.24 with combined surgery. Intraoperatively only 3 eyes had a rupture of the posterior capsule and postoperatively 2 eyes developed malignant glaucoma in the combined group. CONCLUSIONS: The results show that, in eyes with RAM, cataract surgery alone or in combination with glaucoma surgery can be performed with excellent results and low complication rate if adequate precautions are taken (especially the use of hyperosmotic agents).
