Surgical Approach to Retinal and Choroidal Biopsy
Elliot Dean (1)
1. Massachusetts Eye & Ear Infirmary, Harvard Medical School
Chorioretinal biopsy is a useful procedure in cases of retinal and/or choroidal
infiltration of unknown etiology. With the assistance of a skilled pathologist,
the procedure increases the likelihood of diagnosing or excluding certain
conditions such as infection and lymphoma. With proper surgical technique,
the complication rate is low. This presentation will utilize surgical videos to
demonstrate the technique of chorioretinal biopsy in cases that present a
diagnostic challenge.

Processing of the Vitreous, Retina and Choroidal Biopsy
Edward Deepak (1,2)
1. Wilmer Eye Institute, Johns Hopkins University
2. King Khaled Eye Specialist Hospital
The diagnosis of vitreous, retinal and choroidal diseases that are inflammatory,
infectious or neoplastic in nature, can be challenging. Tissue biopsies are
often necessary and are valuable in the diagnosis of such conditions. This
presentation will highlight the methods of obtaining biopsies from these tissues
that are acceptable to the pathologists. The presentation will also include
methods of collection, transportation and specific histologic and molecular
tests each of which will be illustrated using clinical examples.

Choroidal Biopsy in Diagnosis of Uveal Neoplasia
Coupland Sarah (1)
1. University of Liverpool
Aims: To report our experience in choroidal intraocular biopsy for diagnosis of
uveal neoplasia. Methods: Intraocular biopsy may be required to establish the
diagnosis of clinically uncertain choroidal tumours, in particular to differentiate
between primary choroidal and secondary choroidal malignancies. These
biopsies vary in size and complexity, ranging from fine needle aspiration,
25-guage biopsies, endoresections to local resection specimens.
Results: ‹Tips and tricks› for the fixation and processing of intraocular tissue
biopsies are provided. Most solid tissue samples can be placed in buffered
formalin, with the exception of those requiring RNA-based molecular
techniques, here fresh tissue being preferable. The importance of incorporating
data from all investigations and summarizing them as an integrated report is
emphasized. The pitfalls of using any single test (e.g. a molecular genetic test)
as a ‹stand alone› investigation emphasised.
Conclusion: Communication with relevant clinical information between surgeon
and pathologist is essential at each stage: for sample delivery, for exclusion
of differential diagnoses and for rapid result transmission. The current
immunohistochemical and molecular genetic techniques for lymphoma and for
uveal melanoma prognostication are summarized, and how their data can be
used for instigation of individualized management plans for patients discussed

Retinal Biopsy Pathology in Diagnosis of Retina Neoplasia and
Infections
Vitor Vasconcelos Santos Daniel (1)
1. Universidade Federal de Minas Gerais
Retinal biopsy is an important alternative for the definite diagnosis and
adequate management of atypical cases of intraocular inflammation, particularly
those associated with neoplasia or infection. The role of retinal biopsy in such
setting will be discussed, emphasizing the main indications, proper processing
of the specimens and interpretation of the microscopic findings. Illustrative
cases will clinicopathological correlation will also be presented and discussed.

Asian Eyelid Surgery: Pearls and Pitfalls

Finesse in Asian Upper Blepharoplasty
Chee Chew Yip (1)
1. Khoo Teck Puat Hospital Singapore
Asian upper blepharoplasty poses a different surgical challenge to the
oculoplastic surgeon. It is crucial that the anatomical differences between an
Oriental and Occidental eyelid be appreciated so that unique features of the
Asian eyelid are preserved. Careful pre-operative assessment of the patient›s
eyelid anatomy and associated pathology is mandatory. The treatment should
be customised to correct the underlying problems and cater to the patient›s
expectations. Suture blepharoplasty may not always achieve a long lasting or
effective result in some patients.

Managing the Epicanthal Fold: Considerations and Techniques
Tomoyuki Kashima (1)
1. Gunma University
Recurrence of lash globe contact after surgical correction for epiblepharon with
co-existing epicanthic fold had been reported to be high. Prominent epicanthic
folds would aggravate the rolling-in of cilia. We used the Uchida›s method for
epicanthoplasty in Down›s syndrome and Z-plasty for severe epiblepharon,
and combining with the modified Hotz procedure as epiblepharoplasty, and
had achieved successful surgical outcomes. Skin incision is to be carefully
planned and so is meticulous- tissue manipulation, so as to minimize the risks
of unsightly cutaneous scarring post operation.

Surgical Pearls in the Treatment of Cicatricial Entropion
Dong-Mei Li (1)
1. Beijing Tongren Eye Center, Beijing Tongren Hospital, Capital Medical University
Retrospectively evaluate 34 cases with cicatrical entropin. The Hotz tarsotomy
is used in cases of entropion caused by thickening and distortion of tarsus, and
gray-line incision was combined to correct the severe entropion or with topical
misdirection of the eyelashes, some grafts were implanted into dissected grayline.
In patients caused by tarsocojunctival shortening, the involved tarsus
replaced by autogenous tarsocojunctival grafts or allogeneic scleral grafts are
curative. Tarsotomy combined everting sutures allows the eyelids positions
stabilized in the entropion caused by topical cicatricial traction.

Optimising the Success of Congenital Ptosis Surgery
Seah Lay-Leng (1)
1. Singapore National Eye Centre
Long-term success in functional and cosmetic improvements, following
Congenital Ptosis repair, are important for both patients and surgeons. To
achieve a desired post-operative outcome, it is crucial to ensure: accurate preoperative
assessment, appropriate choice of procedures, meticulous tissue
dissection, accurate lid height adjustment, and a good post-operative care. A
thorough pre-operative counseling to manage patients’ expectations, involving
communicating the limitations and risks of surgery, are to be undertaken. Any
co-existing strabismus, refractive error and amblyopia should be treated early.
