Abstract
As a rare congenital disease, microspherophakia (MSP) is characterized by small and spherically shaped crystalline lenses. The common complications of MSP include secondary glaucoma and crystalline lens dislocation or subluxation. Patients with MSP often show high lenticular myopia. The special morphological characteristics and complex complications bring challenges to the treatment of patients with MSP. Although there are some studies on MSP, most are case reports. In this article, the morphological characteristics, complications, genetic diagnosis, and treatment of MSP were systematically reviewed, providing valuable insight into the clinical diagnosis and treatment of this disease.

Abstract
PURPOSE To report the clinical investigation of isolated microspherophakia involving a Senegalese family in order to appreciate its functional impact. OBSERVATIONS This is a rural family comprised of 7 members. The sibship included three girls and two boys. One of the girls, who lived in a distant zone, was unable to be examined. Of all the examined members of the family, only the father was unaffected by the illness. There was no consanguinity. The general medical examination was normal. The best-corrected visual acuity (VA) for the girls was 2/10. For one of the boys, BCVA was 8/10 for both eyes, and for the other, BCVA was 10/10 for the right eye and 8/10 for the left eye. The mother's VA was 10/10 and P2 without correction. Myopia and astigmatism were present in the 4 children of the sibship. During the examination, we noted the presence of small crystalline lenses, which were very round and presented an abnormal visibility of the lens equator and zonular fibers. The diagnosis of microspherophakia was confirmed by measurement of the lens diameters by ultrasound biomicroscopy. Complications were present in the girls, including pupillary block glaucoma and amblyopia for the elder, and retinal degeneration and amblyopia for the younger daughter. The elder daughter was managed medically with glaucoma drops. The younger daughter received optical correction and a prophylactic Argon LASER treatment. The two boys received optical correction. No treatment was recommended for the mother. CONCLUSION Microspherophakia is a rare condition. Some serious complications can lead to amblyopia. A better multidisciplinary evaluation would allow for early detection and a better prognosis.

Abstract
Background: In microspherophakia, abnormal laxity of the lenticular zonules leads to development of a spherical lens and possible subluxation. We evaluated long-term results of lens removal with scleral-fixated intraocular lens (SFIOL) implantation in microspherophakia. Materials and Methods: Case series. SF IOLs were implanted in four consecutive patients with bilateral microspherophakia (eight eyes [three with pupillary block and secondary glaucoma who underwent immediate surgery and five with only subluxation who underwent elective surgery]). Post-operative best-corrected visual acuity (BCVA), intraocular pressure (IOP) and lens position were evaluated periodically from day 1 to 18 months. Results: All patients were females (mean age 28 ± 7.03 years). In group 1 eyes (three eyes that presented with pupillary block), the mean BCVA improved from 0.008 decimals (preoperative) to 0.50 decimals (final post-operative visit); in group 2 eyes (the other five eyes), the mean BCVA improved from 0.12 ± 0.21 decimals to 0.73 ± 0.14 decimals. The preoperative mean IOP (54.53 ± 7.33 mmHg) in group 1 eyes was significantly (P = 0.03) higher than that (16 ± 4.30 mm Hg) in group 2 eyes. At final post-operative visit, the mean IOP (11.67 ± 2.88 mmHg) in group 1 eyes was not significantly different from that in group 2 eyes (13.0 ± 3.08 mmHg). All SFIOLs were well- centred at the final visit. None of the patients encountered any peroperative or postoperative complications. Conclusions: SFIOLs may be an option for surgical management of microspherophakia.
